Fifty years ago, on the night of 10 October1957, Britain was on the brink of an unprecedented nuclear tragedy. A fire ripped through the radioactive materials in the core of Windscale, Britain's first nuclear reactor. Tom Tuohy, the deputy general manager at the site, led the team faced with dealing with a nightmare no-one had thought possible.
"Mankind had never faced a situation like this; there's no-one to give you any advice," he said. Tuohy and his men were confronted by a terrifying dilemma.
If they let the fire burn out, it could spread radioactivity over a large area of Britain. But if they put water on the reactor, they risked turning it into a nuclear bomb that could kill them all.
Now tapes of the inquiry into the accident, heard for the first time in a BBC film, reveal the reasons why the politicians covered up the causes of the accident. Scientists had been warning about the dangers of an accident for some time. The safety margins of the radioactive materials inside the reactor were being further and further eroded.
"They were running much too close to the precipice," says Dr Dunworth, a senior manager in the NuclearResearch Laboratory in Harwell, Oxfordshire, who was one of those highlighting the potential dangers.
But the politicians and the military ignored the warnings; instead they increased demands on Windscale to produce material for an H-bomb.
For 50 years, the official record on the accident has been that the very men who had averted a potentially devastating accident were to blame for causing it.
"I resented it at the time," says Peter Jenkinson, who was an assistant physicist at the reactor, "and I hoped the record would be put straight." After the inquiry, he and his colleagues finally got their wish.

US Army experimental nuclear power reactor SL-1 underwent a steam explosion and meltdown on January 3, 1961, killing its three operators. THIS film explains what was done after the accident was discovered.

http://en.wikipedia.org/wiki/SL-1
The SL-1, or Stationary Low-Power Reactor Number One, was a United States Army experimental nuclear power reactor which underwent a steam explosion and meltdown on January 3, 1961, killing its three operators. The direct cause was the improper withdrawal of the central control rod, responsible for absorbing neutrons in the reactor core. The event is the only known fatal reactor incident in the United States. The incident released about 80 curies (3.0 TBq) of iodine-131, which was not considered significant due to its location in a remote desert of Idaho. About 1,100 curies (41 TBq) of fission products were released into the atmosphere.
The facility, located at the National Reactor Testing Station (NRTS) approximately 40 miles (64 km) west of Idaho Falls, Idaho, was part of the Army Nuclear Power Program and was known as the Argonne Low Power Reactor (ALPR) during its design and build phase. It was intended to provide electrical power and heat for small, remote military facilities, such as radar sites near the Arctic Circle, and those in the DEW Line. The design power was 3 MW (thermal). Operating power was 200 kW electrical and 400 kW thermal for space heating.
In the incident the core power level reached nearly 20 GW in just four milliseconds, precipitating the steam explosion...
From 1954 to 1955, the U.S. Army evaluated their need for nuclear reactor plants that would be operable in remote regions of the Arctic. [The Army] contracted with Argonne National Laboratory to design, build, and test a prototype reactor plant to be called the Argonne Low Power Reactor (ALPR)...
Incident and response
On December 21, 1960, the reactor was shut down for maintenance, calibration of the instruments, installation of auxiliary instruments, and installation of 44 flux wires to monitor the neutron flux levels in the reactor core. The wires were made of aluminum, and contained slugs of aluminum--cobalt alloy.
On January 3, 1961, the reactor was being prepared for restart after a shutdown of eleven days over the holidays. Maintenance procedures were in progress, which required the main central control rod to be manually withdrawn a few inches to reconnect it to its drive mechanism; at 9:01 p.m. this rod was suddenly withdrawn too far, causing SL-1 to go prompt critical instantly. In four milliseconds, the heat generated by the resulting enormous power surge caused water surrounding the core to begin to explosively vaporize. The water vapor caused a pressure wave to strike the top of the reactor vessel, causing water and steam to spray from the top of the vessel. This extreme form of water hammer propelled control rods, shield plugs, and the entire reactor vessel upwards. A later investigation concluded that the 26,000-pound (12,000 kg) vessel had jumped 9 feet 1 inch (2.77 m) and the upper control rod drive mechanisms had struck the ceiling of the reactor building prior to settling back into its original location. The spray of water and steam knocked two operators onto the floor, killing one and severely injuring another. One of the shield plugs on top of the reactor vessel impaled the third man through his groin and exited his shoulder, pinning him to the ceiling. The victims were Army SpecialistsJohn A. Byrnes (age 27) and RichardLeroy McKinley (age 22), and Navy Seabee Construction ElectricianFirst Class (CE1) Richard C. Legg (age 26). It was later established that Byrnes (the reactor operator) had lifted the rod and caused the excursion, Legg (the shift supervisor) was standing on top of the reactor vessel and was impaled and pinned to the ceiling, and McKinley, the trainee who stood nearby, was later found alive by rescuers. All three men succumbed to injuries from physical trauma, however the radiation from the nuclear excursion would have given the men no chance of survival...
There were no other people at the reactor site. The ending of the nuclear reaction was caused solely by the design of the reactor and the basic physics of heated water and core elements melting, separating the core elements and removing the moderator...
The remains of the SL-1 reactor are now buried near the original site...

11. GoianiaAccident, Brazil
One of the worst nuclear contamination incidents in the world took place in Goiania, Brazil. A radiotherapy institute in the city had relocated, leaving behind a teletherapy unit that still contained cesium chloride.
On September 13, 1987, two scavengers found the unit, carted it away in a wheelbarrow, and sold it to a junkyard. The owner invited friends and family to see the glowing blue material inside, inadvertently exposing them to radiation. All of them then went their separate ways and irradiated friends and family all over the city.
In all, 245 people were exposed to radiation and four people passed. It raised awareness that sources of radiation must be controlled from ‘cradle to grave’ to prevent the public accessing them.
10. Windscale Pile, EnglandBritain needed plutonium and other materials for the country’s burgeoning nuclear weapons. In the late 1940s, they built their first nuclear reactor, called Windscale, in northwest England. On October 10, 1957, workers conducting standard maintenance at the massive facility noticed rising temperatures. Upon further inspection, they discovered that the reactor’s uranium-filled graphite core had caught fire. Worse, it had likely been ablaze for two days, releasing dangerous contaminants into the atmosphere.
With the reactor on the verge of collapse, plant operators fought the flames with cooling fans, carbon dioxide, and water. The fire finally died out on October 12, but by that time, a radioactive cloud was already spreading across the United Kingdom and Europe.
While no evacuations occurred, officials prohibited the sale of milk from the affected area for roughly a month. An investigation discovered the accident had been both avoidable and mishandled. The British government suppressed the complete report for several decades, however, in part because it may have compromised Britain’s efforts to cooperate with the United States on nuclear development. In 2007, a study estimated that the radioactive fallout from the Windscale fire might have caused some 240 cases of cancer.
9. Three Mile Island, Pennsylvania
The most serious nuclear accident in U.S. history took place at the Three Mile Island plant near Harrisburg, Pennsylvania, a brand-new facility lauded for its state-of-the-art design, efficiency and affordability during an era of energy crises. It began in the early hours of the morning, when a pressure valve in one of the reactors failed to close, allowing cooling water–contaminated with radiation–to drain into adjoining buildings. Control room operators made critical errors as they struggled to contain the crisis, and the core had heated to over 4,000 degrees–just 1,000 degrees short of meltdown.
As radioactive steam began pouring out of the plant, word of the incident leaked to the outside world. The plant’s parent company downplayed the event, claiming that no radiation had been detected off plant grounds. However, within days radiation levels were elevated over a four-county zone. Pennsylvania GovernorRichard Thornburgh ordered the evacuation of pregnant women and small children from the area.
The incident also eroded the American public’s faith in nuclear power, inspiring many demonstrations, and increased awareness of the need for emergency preparedness at the state and local levels. Over 50 nuclear plant construction projects were cancelled in just four years, and the number of ongoing projects declined from 1980 until 1998.

On April 26, 2016, Ukraine marked the sad 30th anniversary of the Chornobyl nuclear disaster.
The Chernobyl disaster was a catastrophic nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in the city of Pripyat, then located in the Ukrainian Soviet Socialist Republic of the Soviet Union (USSR). An explosion and fire released large quantities of radioactive particles into the atmosphere, which spread over much of the western USSR and Europe.
https://en.wikipedia.org/wiki/Chernobyl_disaster
Moscow tried to hide the disaster for 2 days before finally admitting the accident. Evacuation began long before the accident was publicly known throughout the Union. Only on 28 April, after radiation levels set off alarms at the Forsmark Nuclear Power Plant in Sweden, over 1,000 kilometres (620 mi) from the Chernobyl Plant, did the Soviet Union publicly admit that an accident had occurred. At 21:02 that evening a 20-second announcement was read in the TV news program Vremya:
There has been an accident at the Chernobyl Nuclear Power Plant. One of the nuclear reactors was damaged. The effects of the accident are being remedied. Assistance has been provided for any affected people. An investigative commission has been set up.
— Vremya, 28 April 1986 (21:00)
This was the entirety of the announcement of the accident.
The nearby city of Pripyat was not immediately evacuated. The townspeople went about their usual business, completely oblivious to what had just happened. By 11:00 on 27 April, buses had arrived in Pripyat to start the evacuation.
Thirty-one deaths are directly attributed to the accident, all among the reactor staff and emergency workers. An UNSCEAR report places the total confirmed deaths from radiation at 64 as of 2008. The Chernobyl Forum predicts the eventual death toll could reach 4,000 among those exposed to the highest levels of radiation (200,000 emergency workers, 116,000 evacuees and 270,000 residents of the most contaminated areas).
The soundtrack is "Ethnicolor 1" by Jean Michel Jarre.

The impact of nuclear accidents has been a topic of debate practically since the first nuclear reactors were constructed in 1954. It has also been a key factor in public concern about nuclear facilities. Some technical measures to reduce the risk of accidents or to minimize the amount of radioactivity released to the environment have been adopted. Despite the use of such measures, human error remains, and "there have been many accidents with varying impacts as well near misses and incidents".

Nuclear (fission) power stations, excluding the contribution from naval nuclear fission reactors, provided 11% of the world's electricity in 2012, somewhat less than that generated by hydro-electric stations at 16%. Since electricity accounts for about 25% of humanity's energy usage with the majority of the rest coming from fossil fuel reliant sectors such as transport, manufacture and home heating, nuclear fission's contribution to the global final energy consumption is about 2.5%, a little more than the combined global electricity production from "new renewables"; wind, solar, biofuel and geothermal power, which together provided 2% of global final energy consumption in 2014.

Compilation of Rare 1986 Videos of Chernobyl Disaster. (English)

On April 26, 2016, Ukraine marked the sad 30th anniversary of the Chornobyl nuclear disaster.
The Chernobyl disaster was a catastrophic nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in the city of Pripyat, then located in the Ukrainian Soviet Socialist Republic of the Soviet Union (USSR). An explosion and fire released large quantities of radioactive particles into the atmosphere, which spread over much of the western USSR and Europe.
https://en.wikipedia.org/wiki/Chernobyl_disaster
Moscow tried to hide the disaster for 2 days before finally admitting the accident. Evacuation began long before the accident was publicly known throughout the Union. Only on 28 April, after radiation levels set off alarms at the Forsmark Nuclear Power Plant in Sweden, over 1,000 kilometres (620 mi) from the Chernobyl Plant, did the Soviet Union publicly admit that an accident had occurred. At 21:02 that evening a 20-second announcement was read in the TV news program Vremya:
There has been an accident at the Chernobyl Nuclear Power Plant. One of the nuclear reactors was damaged. The effects of the accident are being remedied. Assistance has been provided for any affected people. An investigative commission has been set up.
— Vremya, 28 April 1986 (21:00)
This was the entirety of the announcement of the accident.
The nearby city of Pripyat was not immediately evacuated. The townspeople went about their usual business, completely oblivious to what had just happened. By 11:00 on 27 April, buses had arrived in Pripyat to start the evacuation.
Thirty-one deaths are directly attributed to the accident, all among the reactor staff and emergency workers. An UNSCEAR report places the total confirmed deaths from radiation at 64 as of 2008. The Chernobyl Forum predicts the eventual death toll could reach 4,000 among those exposed to the highest levels of radiation (200,000 emergency workers, 116,000 evacuees and 270,000 residents of the most contaminated areas).
The soundtrack is "Ethnicolor 1" by Jean Michel Jarre.

The DemonCore was the nickname given to a 6.2-kilogram (14 lb) subcritical mass of plutonium that accidentally went critical on two separate instances at the Los Alamos laboratory in 1945 and 1946. Each incident resulted in the acute radiation poisoning and subsequent death of a scientist. After these incidents the mass of plutonium was referred to as the Demon Core.
The Slotin and Daghlian incidents were combined and fictionalized in the film Fat Man and Little Boy.

On January 3 1961SL1 reactor was being prepared for a restart following a maintenance outage. The control rods were being withdrawn to reconnect them to the drive mechanism, when suddenly one rod was removed to far, causing the reactor to become prompt-critical. The resulting power surge led to an explosive vaporization of the water, which in turn created a water hammer, ejecting the control rods and the shield plugs.

The Battle Of Chernobyl (Full Documentary)

The Battle Of Chernobyl (Full Documentary)

The Battle Of Chernobyl (Full Documentary)

The Chernobyl disaster was a catastrophic nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine (then officially the Ukrainian SSR), which was under the direct jurisdiction of the central authorities of the Soviet Union. An explosion and fire released large quantities of radioactive particles into the atmosphere, which spread over much of the western USSR and Europe.
The Chernobyl disaster is widely considered to have been the worst nuclear power plant accident in history, and is one of only two classified as a level 7 event (the maximum classification) on the International Nuclear Event Scale (the other being the Fukushima Daiichi nuclear disaster in 2011).
The battle to contain the contamination and avert a greater catastrophe ultimately involved over 500,000 workers and cost an estimated 18 billion rubles.The official Soviet casualty count of 31 deaths has been disputed, and long-term effects such as cancers and deformities are still being accounted for.
It's a documentary which analyzes the Thursday 26th April1986 that became a momentous date in modern history, when one of the reactors at the Chernobyl nuclear power station in northern Ukraine, exploded. It was the most significant reactor failure in the history of nuclear power, a Maximum Credible Accident (MCA). The plant, just 20 km away from the town center, was made up of four reactor units each generating an output of 1,000 megawatts. The reactor in question exploded due to operational errors and inadequate safety measures and the meltdown was directly linked to routine testing on the reactor unit's turbine generators.
The test required reactor activity and the thermal reactor output to be run down to a lower level. During the procedure, however, the reactor plummeted to an unexpectedly low and unstable level of activity. At this point, it should have been shut down; as the operators chose to continue with the test, the events subsequently proved to be catastrophic.
More than 200 people died or were seriously injured by radiation exposure immediately after the explosion. 161,000 people had to be evacuated from a 30 kilometer radius of the reactor and 25,000 square km of land were contaminated. As time went on millions of people suffered radiation related health problems such as leukemia and thyroid cancer and around 4,000 people have died as a result of the long-term effects of the accident.
Nobody was prepared for such a crisis. For the next seven months, 500,000 men will wage hand-to-hand combat with an invisible enemy -- a ruthless battle that has gone unsung, which claimed thousands of unnamed and now almost forgotten heroes. Yet, it is thanks to these men that the worst was avoided; a second explosion, ten times more powerful than Hiroshima which would have wiped out more than half of Europe. This was kept secret for twenty years by the Soviets and the West alike.

http://en.wikipedia.org/wiki/SL-1
The SL-1, or Stationary Low-Power Reactor Number One, was a United States Army experimental nuclear power reactor which underwent a steam explosion and meltdown on January 3, 1961, killing its three operators. The direct cause was the improper withdrawal of the central control rod, responsible for absorbing neutrons in the reactor core. The event is the only known fatal reactor incident in the United States. The incident released about 80 curies (3.0 TBq) of iodine-131, which was not considered significant due to its location in a remote desert of Idaho. About 1,100 curies (41 TBq) of fission products were released into the atmosphere.
The facility, located at the National Reactor Testing Station (NRTS) approximately 40 miles (64 km) west of Idaho Falls, Idaho, was part of the Army Nuclear Power Program and was known as the Argonne Low Power Reactor (ALPR) during its design and build phase. It was intended to provide electrical power and heat for small, remote military facilities, such as radar sites near the Arctic Circle, and those in the DEW Line. The design power was 3 MW (thermal). Operating power was 200 kW electrical and 400 kW thermal for space heating.
In the incident the core power level reached nearly 20 GW in just four milliseconds, precipitating the steam explosion...
From 1954 to 1955, the U.S. Army evaluated their need for nuclear reactor plants that would be operable in remote regions of the Arctic. [The Army] contracted with Argonne National Laboratory to design, build, and test a prototype reactor plant to be called the Argonne Low Power Reactor (ALPR)...
Incident and response
On December 21, 1960, the reactor was shut down for maintenance... and installation of 44 flux wires to monitor the neutron flux levels in the reactor core. The wires were made of aluminum, and contained slugs of aluminum--cobalt alloy.
On January 3, 1961, the reactor was being prepared for restart after a shutdown of eleven days over the holidays. Maintenance procedures were in progress, which required the main central control rod to be manually withdrawn a few inches to reconnect it to its drive mechanism; at 9:01 p.m. this rod was suddenly withdrawn too far, causing SL-1 to go prompt critical instantly. In four milliseconds, the heat generated by the resulting enormous power surge caused water surrounding the core to begin to explosively vaporize. The water vapor caused a pressure wave to strike the top of the reactor vessel, causing water and steam to spray from the top of the vessel. This extreme form of water hammer propelled control rods, shield plugs, and the entire reactor vessel upwards. A later investigation concluded that the 26,000-pound (12,000 kg) vessel had jumped 9 feet 1 inch (2.77 m) and the upper control rod drive mechanisms had struck the ceiling of the reactor building prior to settling back into its original location. The spray of water and steam knocked two operators onto the floor, killing one and severely injuring another. One of the shield plugs on top of the reactor vessel impaled the third man through his groin and exited his shoulder, pinning him to the ceiling. The victims were Army SpecialistsJohn A. Byrnes (age 27) and RichardLeroy McKinley (age 22), and Navy Seabee Construction ElectricianFirst Class (CE1) Richard C. Legg (age 26). It was later established that Byrnes (the reactor operator) had lifted the rod and caused the excursion, Legg (the shift supervisor) was standing on top of the reactor vessel and was impaled and pinned to the ceiling, and McKinley, the trainee who stood nearby, was later found alive by rescuers. All three men succumbed to injuries from physical trauma, however the radiation from the nuclear excursion would have given the men no chance of survival...
There were no other people at the reactor site. The ending of the nuclear reaction was caused solely by the design of the reactor and the basic physics of heated water and core elements melting, separating the core elements and removing the moderator...
The remains of the SL-1 reactor are now buried near the original site...

Fifty years ago, on the night of 10 October1957, Britain was on the brink of an unprecedented nuclear tragedy. A fire ripped through the radioactive materials in the core of Windscale, Britain's first nuclear reactor. Tom Tuohy, the deputy general manager at the site, led the team faced with dealing with a nightmare no-one had thought possible.
"Mankind had never faced a situation like this; there's no-one to give you any advice," he said. Tuohy and his men were confronted by a terrifying dilemma.
If they let the fire burn out, it could spread radioactivity over a large area of Britain. But if they put water on the reactor, they risked turning it into a nuclear bomb that could kill them all.

Fifty years ago, on the night of 10 October1957, Britain was on the brink of an unprecedented nuclear tragedy. A fire ripped through the radioactive materials in the core of Windscale, Britain's first nuclear reactor. Tom Tuohy, the deputy general manager at the site, led the team faced with dealing with a nightmare no-one had thought possible.
"Mankind had never faced a situation like this; there's no-one to give you any advice," he said. Tuohy and his men were confronted by a terrifying dilemma.
If they let the fire burn out, it could spread radioactivity over a large area of Britain. But if they put water on the reactor, they risked turning it into a nuclear bomb that could kill them all.
Now tapes of the inquiry into the accident, heard for the first time in a BBC film, reveal the reasons why the politicians covered up the causes of the accident. Scientists had been warning about the dangers of an accident for some time. The safety margins of the radioactive materials inside the reactor were being further and further eroded.
"They were running much too close to the precipice," says Dr Dunworth, a senior manager in the NuclearResearch Laboratory in Harwell, Oxfordshire, who was one of those highlighting the potential dangers.
But the politicians and the military ignored the warnings; instead they increased demands on Windscale to produce material for an H-bomb.
For 50 years, the official record on the accident has been that the very men who had averted a potentially devastating accident were to blame for causing it.
"I resented it at the time," says Peter Jenkinson, who was an assistant physicist at the reactor, "and I hoped the record would be put straight." After the inquiry, he and his colleagues finally got their wish.

http://en.wikipedia.org/wiki/SL-1
The SL-1, or Stationary Low-Power Reactor Number One, was a United States Army experimental nuclear power reactor which underwent a steam explosion and meltdown on January 3, 1961, killing its three operators. The direct cause was the improper withdrawal of the central control rod, responsible for absorbing neutrons in the reactor core. The event is the only known fatal reactor incident in the United States. The incident released about 80 curies (3.0 TBq) of iodine-131, which was not considered significant due to its location in a remote desert of Idaho. About 1,100 curies (41 TBq) of fission products were released into the atmosphere.
The facility, located at the National Reactor Testing Station (NRTS) approximately 40 miles (64 km) west of Idaho Falls, Idaho, was part of the Army Nuclear Power Program and was known as the Argonne Low Power Reactor (ALPR) during its design and build phase. It was intended to provide electrical power and heat for small, remote military facilities, such as radar sites near the Arctic Circle, and those in the DEW Line. The design power was 3 MW (thermal). Operating power was 200 kW electrical and 400 kW thermal for space heating.
In the incident the core power level reached nearly 20 GW in just four milliseconds, precipitating the steam explosion...
From 1954 to 1955, the U.S. Army evaluated their need for nuclear reactor plants that would be operable in remote regions of the Arctic. [The Army] contracted with Argonne National Laboratory to design, build, and test a prototype reactor plant to be called the Argonne Low Power Reactor (ALPR)...
Incident and response
On December 21, 1960, the reactor was shut down for maintenance, calibration of the instruments, installation of auxiliary instruments, and installation of 44 flux wires to monitor the neutron flux levels in the reactor core. The wires were made of aluminum, and contained slugs of aluminum--cobalt alloy.
On January 3, 1961, the reactor was being prepared for restart after a shutdown of eleven days over the holidays. Maintenance procedures were in progress, which required the main central control rod to be manually withdrawn a few inches to reconnect it to its drive mechanism; at 9:01 p.m. this rod was suddenly withdrawn too far, causing SL-1 to go prompt critical instantly. In four milliseconds, the heat generated by the resulting enormous power surge caused water surrounding the core to begin to explosively vaporize. The water vapor caused a pressure wave to strike the top of the reactor vessel, causing water and steam to spray from the top of the vessel. This extreme form of water hammer propelled control rods, shield plugs, and the entire reactor vessel upwards. A later investigation concluded that the 26,000-pound (12,000 kg) vessel had jumped 9 feet 1 inch (2.77 m) and the upper control rod drive mechanisms had struck the ceiling of the reactor building prior to settling back into its original location. The spray of water and steam knocked two operators onto the floor, killing one and severely injuring another. One of the shield plugs on top of the reactor vessel impaled the third man through his groin and exited his shoulder, pinning him to the ceiling. The victims were Army SpecialistsJohn A. Byrnes (age 27) and RichardLeroy McKinley (age 22), and Navy Seabee Construction ElectricianFirst Class (CE1) Richard C. Legg (age 26). It was later established that Byrnes (the reactor operator) had lifted the rod and caused the excursion, Legg (the shift supervisor) was standing on top of the reactor vessel and was impaled and pinned to the ceiling, and McKinley, the trainee who stood nearby, was later found alive by rescuers. All three men succumbed to injuries from physical trauma, however the radiation from the nuclear excursion would have given the men no chance of survival...
There were no other people at the reactor site. The ending of the nuclear reaction was caused solely by the design of the reactor and the basic physics of heated water and core elements melting, separating the core elements and removing the moderator...
The remains of the SL-1 reactor are now buried near the original site...

11. GoianiaAccident, Brazil
One of the worst nuclear contamination incidents in the world took place in Goiania, Brazil. A radiotherapy institute in the city had relocated, leaving behind a teletherapy unit that still contained cesium chloride.
On September 13, 1987, two scavengers found the unit, carted it away in a wheelbarrow, and sold it to a junkyard. The owner invited friends and family to see the glowing blue material inside, inadvertently exposing them to radiation. All of them then went their separate ways and irradiated friends and family all over the city.
In all, 245 people were exposed to radiation and four people passed. It raised awareness that sources of radiation must be controlled from ‘cradle to grave’ to prevent the public accessing them.
10. Windscale Pile, EnglandBritain needed plutonium and other materials for the country’s burgeoning nuclear weapons. In the late 1940s, they built their first nuclear reactor, called Windscale, in northwest England. On October 10, 1957, workers conducting standard maintenance at the massive facility noticed rising temperatures. Upon further inspection, they discovered that the reactor’s uranium-filled graphite core had caught fire. Worse, it had likely been ablaze for two days, releasing dangerous contaminants into the atmosphere.
With the reactor on the verge of collapse, plant operators fought the flames with cooling fans, carbon dioxide, and water. The fire finally died out on October 12, but by that time, a radioactive cloud was already spreading across the United Kingdom and Europe.
While no evacuations occurred, officials prohibited the sale of milk from the affected area for roughly a month. An investigation discovered the accident had been both avoidable and mishandled. The British government suppressed the complete report for several decades, however, in part because it may have compromised Britain’s efforts to cooperate with the United States on nuclear development. In 2007, a study estimated that the radioactive fallout from the Windscale fire might have caused some 240 cases of cancer.
9. Three Mile Island, Pennsylvania
The most serious nuclear accident in U.S. history took place at the Three Mile Island plant near Harrisburg, Pennsylvania, a brand-new facility lauded for its state-of-the-art design, efficiency and affordability during an era of energy crises. It began in the early hours of the morning, when a pressure valve in one of the reactors failed to close, allowing cooling water–contaminated with radiation–to drain into adjoining buildings. Control room operators made critical errors as they struggled to contain the crisis, and the core had heated to over 4,000 degrees–just 1,000 degrees short of meltdown.
As radioactive steam began pouring out of the plant, word of the incident leaked to the outside world. The plant’s parent company downplayed the event, claiming that no radiation had been detected off plant grounds. However, within days radiation levels were elevated over a four-county zone. Pennsylvania GovernorRichard Thornburgh ordered the evacuation of pregnant women and small children from the area.
The incident also eroded the American public’s faith in nuclear power, inspiring many demonstrations, and increased awareness of the need for emergency preparedness at the state and local levels. Over 50 nuclear plant construction projects were cancelled in just four years, and the number of ongoing projects declined from 1980 until 1998.

On April 26, 2016, Ukraine marked the sad 30th anniversary of the Chornobyl nuclear disaster.
The Chernobyl disaster was a catastrophic nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in the city of Pripyat, then located in the Ukrainian Soviet Socialist Republic of the Soviet Union (USSR). An explosion and fire released large quantities of radioactive particles into the atmosphere, which spread over much of the western USSR and Europe.
https://en.wikipedia.org/wiki/Chernobyl_disaster
Moscow tried to hide the disaster for 2 days before finally admitting the accident. Evacuation began long before the accident was publicly known throughout the Union. Only on 28 April, after radiation levels set off alarms at the Forsmark Nuclear Power Plant in Sweden, over 1,000 kilometres (620 mi) from the Chernobyl Plant, did the Soviet Union publicly admit that an accident had occurred. At 21:02 that evening a 20-second announcement was read in the TV news program Vremya:
There has been an accident at the Chernobyl Nuclear Power Plant. One of the nuclear reactors was damaged. The effects of the accident are being remedied. Assistance has been provided for any affected people. An investigative commission has been set up.
— Vremya, 28 April 1986 (21:00)
This was the entirety of the announcement of the accident.
The nearby city of Pripyat was not immediately evacuated. The townspeople went about their usual business, completely oblivious to what had just happened. By 11:00 on 27 April, buses had arrived in Pripyat to start the evacuation.
Thirty-one deaths are directly attributed to the accident, all among the reactor staff and emergency workers. An UNSCEAR report places the total confirmed deaths from radiation at 64 as of 2008. The Chernobyl Forum predicts the eventual death toll could reach 4,000 among those exposed to the highest levels of radiation (200,000 emergency workers, 116,000 evacuees and 270,000 residents of the most contaminated areas).
The soundtrack is "Ethnicolor 1" by Jean Michel Jarre.

The DemonCore was the nickname given to a 6.2-kilogram (14 lb) subcritical mass of plutonium that accidentally went critical on two separate instances at the Los Alamos laboratory in 1945 and 1946. Each incident resulted in the acute radiation poisoning and subsequent death of a scientist. After these incidents the mass of plutonium was referred to as the Demon Core.
The Slotin and Daghlian incidents were combined and fictionalized in the film Fat Man and Little Boy.

On January 3 1961SL1 reactor was being prepared for a restart following a maintenance outage. The control rods were being withdrawn to reconnect them to the drive mechanism, when suddenly one rod was removed to far, causing the reactor to become prompt-critical. The resulting power surge led to an explosive vaporization of the water, which in turn created a water hammer, ejecting the control rods and the shield plugs.

The Chernobyl disaster was a catastrophic nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine (then officially the Ukrainian SSR), which was under the direct jurisdiction of the central authorities of the Soviet Union. An explosion and fire released large quantities of radioactive particles into the atmosphere, which spread over much of the western USSR and Europe.
The Chernobyl disaster is widely considered to have been the worst nuclear power plant accident in history, and is one of only two classified as a level 7 event (the maximum classification) on the International Nuclear Event Scale (the other being the Fukushima Daiichi nuclear disaster in 2011).
The battle to contain the contamination and avert a greater catastrophe ultimately involved over 500,000 workers and cost an estimated 18 billion rubles.The official Soviet casualty count of 31 deaths has been disputed, and long-term effects such as cancers and deformities are still being accounted for.
It's a documentary which analyzes the Thursday 26th April1986 that became a momentous date in modern history, when one of the reactors at the Chernobyl nuclear power station in northern Ukraine, exploded. It was the most significant reactor failure in the history of nuclear power, a Maximum Credible Accident (MCA). The plant, just 20 km away from the town center, was made up of four reactor units each generating an output of 1,000 megawatts. The reactor in question exploded due to operational errors and inadequate safety measures and the meltdown was directly linked to routine testing on the reactor unit's turbine generators.
The test required reactor activity and the thermal reactor output to be run down to a lower level. During the procedure, however, the reactor plummeted to an unexpectedly low and unstable level of activity. At this point, it should have been shut down; as the operators chose to continue with the test, the events subsequently proved to be catastrophic.
More than 200 people died or were seriously injured by radiation exposure immediately after the explosion. 161,000 people had to be evacuated from a 30 kilometer radius of the reactor and 25,000 square km of land were contaminated. As time went on millions of people suffered radiation related health problems such as leukemia and thyroid cancer and around 4,000 people have died as a result of the long-term effects of the accident.
Nobody was prepared for such a crisis. For the next seven months, 500,000 men will wage hand-to-hand combat with an invisible enemy -- a ruthless battle that has gone unsung, which claimed thousands of unnamed and now almost forgotten heroes. Yet, it is thanks to these men that the worst was avoided; a second explosion, ten times more powerful than Hiroshima which would have wiped out more than half of Europe. This was kept secret for twenty years by the Soviets and the West alike.

The test required reactor activity and the thermal reactor output to be run down to a lower level. During the procedure, however, the reactor plummeted to an unexpectedly low and unstable level of activity. At this point, it should have been shut down; as the operators chose to continue with the test, the events subsequently proved to be catastrophic.
More than 200 people died or were seriously injured by radiation exposure immediately after the explosion. 161,000 people had to be evacuated from a 30 kilometer radius of the reactor and 25,000 square km of land were contaminated. As time went on millions of people suffered radiation related health problems such as leukemia and thyroid cancer and around 4,000 people have died as a result of the long-term effects of the accident.
Nobody was prepared for such a crisis. For the next seven months, 500,000 men will wage hand-to-hand combat with an invisible enemy -- a ruthless battle that has gone unsung, which claimed thousands of unnamed and now almost forgotten heroes. Yet, it is thanks to these men that the worst was avoided; a second explosion, ten times more powerful than Hiroshima which would have wiped out more than half of Europe. This was kept secret for twenty years by the Soviets and the West alike.

The SL-1, or Stationary Low-Power Reactor Number One, was a United States Army experimental nuclear power reactor which underwent a steam explosion and meltdown on January 3, 1961, killing its three operators. The direct cause was the improper withdrawal of the central control rod, responsible for absorbing neutrons in the reactor core. The event is the only known fatal reactor incident in the United States. The incident released about 80 curies (3.0 TBq) of iodine-131, which was not considered significant due to its location in a remote desert of Idaho. About 1,100 curies (41 TBq) of fission products were released into the atmosphere.
The facility, located at the National Reactor Testing Station (NRTS) approximately 40 miles (64 km) west of Idaho Falls, Idaho, was part of the Army Nuclear Power Program and was known as the Argonne Low Power Reactor (ALPR) during its design and build phase. It was intended to provide electrical power and heat for small, remote military facilities, such as radar sites near the Arctic Circle, and those in the DEW Line. The design power was 3 MW (thermal). Operating power was 200 kW electrical and 400 kW thermal for space heating.

Incident and response
On December 21, 1960, the reactor was shut down for maintenance... and installation of 44 flux wires to monitor the neutron flux levels in the reactor core. The wires were made of aluminum, and contained slugs of aluminum--cobalt alloy.
On January 3, 1961, the reactor was being prepared for restart after a shutdown of eleven days over the holidays. Maintenance procedures were in progress, which required the main central control rod to be manually withdrawn a few inches to reconnect it to its drive mechanism; at 9:01 p.m. this rod was suddenly withdrawn too far, causing SL-1 to go prompt critical instantly. In four milliseconds, the heat generated by the resulting enormous power surge caused water surrounding the core to begin to explosively vaporize. The water vapor caused a pressure wave to strike the top of the reactor vessel, causing water and steam to spray from the top of the vessel. This extreme form of water hammer propelled control rods, shield plugs, and the entire reactor vessel upwards. A later investigation concluded that the 26,000-pound (12,000 kg) vessel had jumped 9 feet 1 inch (2.77 m) and the upper control rod drive mechanisms had struck the ceiling of the reactor building prior to settling back into its original location. The spray of water and steam knocked two operators onto the floor, killing one and severely injuring another. One of the shield plugs on top of the reactor vessel impaled the third man through his groin and exited his shoulder, pinning him to the ceiling. The victims were Army SpecialistsJohn A. Byrnes (age 27) and RichardLeroy McKinley (age 22), and Navy Seabee Construction ElectricianFirst Class (CE1) Richard C. Legg (age 26). It was later established that Byrnes (the reactor operator) had lifted the rod and caused the excursion, Legg (the shift supervisor) was standing on top of the reactor vessel and was impaled and pinned to the ceiling, and McKinley, the trainee who stood nearby, was later found alive by rescuers.

Fifty years ago, on the night of 10 October1957, Britain was on the brink of an unprecedented nuclear tragedy. A fire ripped through the radioactive materials in the core of Windscale, Britain's first nuclear reactor. Tom Tuohy, the deputy general manager at the site, led the team faced with dealing with a nightmare no-one had thought possible.
"Mankind had never faced a situation like this; there's no-one to give you any advice," he said. Tuohy and his men were confronted by a terrifying dilemma.

SL1 Accident (1961)

On January 3 1961SL1 reactor was being prepared for a restart following a maintenance outage. The control rods were being withdrawn to reconnect them to the drive mechanism, when suddenly one rod was removed to far, causing the reactor to become prompt-critical. The resulting power surge led to an explosive vaporization of the water, which in turn created a water hammer, ejecting the control rods and the shield plugs.

Named after the Buddhist divinity of wisdom, Monju, located in Japan's Fukui prefecture, is Japan's only fast-breeder reactor. Unlike conventional reactors, fast-breeder reactors, which "breed" plutonium, use sodium rather than water as a coolant. This type of coolant creates a potentially hazardous situation as sodium is highly corrosive and reacts violently with both water and air.
On December 8th, 1995, 700 kg of molten sodium leaked from the secondary cooling circuit of the Monju reactor, resulting in a fire that made headlines across the country. Although the accident itself did not result in a radiation leak, many argue that the fire came close to breaching Monju, a catastrophe which would have spilled plutonium into the environment.
Following the fire, officials at the government-...

Fukushima Nuclear Accident Documentary

The Fukushima disaster is the largest nuclear disaster since the 1986 Chernobyl disaster and the second disaster to be given the Level 7 event classification of the International Nuclear Event Scale. Though there have been no fatalities linked to radiation due to the accident, the eventual number of cancer deaths, according to the linear no-threshold theory of radiation safety, that will be caused by the accident is expected to be around 130-640 people in the years and decades ahead. The United Nations Scientific Committee on the Effects of AtomicRadiation and World Health Organization report that there will be no increase in miscarriages, stillbirths or physical and mental disorders in babies born after the accident. However, an estimated 1,600 deaths are believed to have occurred due to...

Fifty years ago, on the night of 10 October1957, Britain was on the brink of an unprecedented nuclear tragedy. A fire ripped through the radioactive materials in the core of Windscale, Britain's first nuclear reactor. Tom Tuohy, the deputy general manager at the site, led the team faced with dealing with a nightmare no-one had thought possible.
"Mankind had never faced a situation like this; there's no-one to give you any advice," he said. Tuohy and his men were confronted by a terrifying dilemma.
If they let the fire burn out, it could spread radioactivity over a large area of Britain. But if they put water on the reactor, they risked turning it into a nuclear bomb that could kill them all.
Now tapes of the inquiry into the accident, heard for the first time in a BBC film, reveal the reasons why the politicians covered up the causes of the accident. Scientists had been warning about the dangers of an accident for some time. The safety margins of the radioactive materials inside the reactor were being further and further eroded.
"They were running much too close to the precipice," says Dr Dunworth, a senior manager in the NuclearResearch Laboratory in Harwell, Oxfordshire, who was one of those highlighting the potential dangers.
But the politicians and the military ignored the warnings; instead they increased demands on Windscale to produce material for an H-bomb.
For 50 years, the official record on the accident has been that the very men who had averted a potentially devastating accident were to blame for causing it.
"I resented it at the time," says Peter Jenkinson, who was an assistant physicist at the reactor, "and I hoped the record would be put straight." After the inquiry, he and his colleagues finally got their wish.

On December 21, 1960, the reactor was shut down for maintenance, calibration of the instruments, installation of auxiliary instruments, and installation of 44 flux wires to monitor the neutron flux levels in the reactor core. The wires were made of aluminum, and contained slugs of aluminum--cobalt alloy.
On January 3, 1961, the reactor was being prepared for restart after a shutdown of eleven days over the holidays. Maintenance procedures were in progress, which required the main central control rod to be manually withdrawn a few inches to reconnect it to its drive mechanism; at 9:01 p.m. this rod was suddenly withdrawn too far, causing SL-1 to go prompt critical instantly. In four milliseconds, the heat generated by the resulting enormous power surge caused water surrounding the core to begin to explosively vaporize. The water vapor caused a pressure wave to strike the top of the reactor vessel, causing water and steam to spray from the top of the vessel. This extreme form of water hammer propelled control rods, shield plugs, and the entire reactor vessel upwards. A later investigation concluded that the 26,000-pound (12,000 kg) vessel had jumped 9 feet 1 inch (2.77 m) and the upper control rod drive mechanisms had struck the ceiling of the reactor building prior to settling back into its original location. The spray of water and steam knocked two operators onto the floor, killing one and severely injuring another. One of the shield plugs on top of the reactor vessel impaled the third man through his groin and exited his shoulder, pinning him to the ceiling. The victims were Army SpecialistsJohn A. Byrnes (age 27) and RichardLeroy McKinley (age 22), and Navy Seabee Construction ElectricianFirst Class (CE1) Richard C. Legg (age 26). It was later established that Byrnes (the reactor operator) had lifted the rod and caused the excursion, Legg (the shift supervisor) was standing on top of the reactor vessel and was impaled and pinned to the ceiling, and McKinley, the trainee who stood nearby, was later found alive by rescuers. All three men succumbed to injuries from physical trauma, however the radiation from the nuclear excursion would have given the men no chance of survival...
There were no other people at the reactor site. The ending of the nuclear reaction was caused solely by the design of the reactor and the basic physics of heated water and core elements melting, separating the core elements and removing the moderator...
The remains of the SL-1 reactor are now buried near the original site...

The Chernobyl disaster was a catastrophic nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine (then officially the Ukrainian SSR), which was under the direct jurisdiction of the central authorities of the Soviet Union. An explosion and fire released large quantities of radioactive particles into the atmosphere, which spread over much of the western USSR and Europe.
The Chernobyl disaster is widely considered to have been the worst nuclear power plant accident in history, and is one of only two classified as a level 7 event (the maximum classification) on the International Nuclear Event Scale (the other being the Fukushima Daiichi nuclear disaster in 2011).
The battle to contain the contamination and avert a greater catastrophe ultimately involved over 500,000 workers and cost an estimated 18 billion rubles.The official Soviet casualty count of 31 deaths has been disputed, and long-term effects such as cancers and deformities are still being accounted for.
It's a documentary which analyzes the Thursday 26th April1986 that became a momentous date in modern history, when one of the reactors at the Chernobyl nuclear power station in northern Ukraine, exploded. It was the most significant reactor failure in the history of nuclear power, a Maximum Credible Accident (MCA). The plant, just 20 km away from the town center, was made up of four reactor units each generating an output of 1,000 megawatts. The reactor in question exploded due to operational errors and inadequate safety measures and the meltdown was directly linked to routine testing on the reactor unit's turbine generators.
The test required reactor activity and the thermal reactor output to be run down to a lower level. During the procedure, however, the reactor plummeted to an unexpectedly low and unstable level of activity. At this point, it should have been shut down; as the operators chose to continue with the test, the events subsequently proved to be catastrophic.
More than 200 people died or were seriously injured by radiation exposure immediately after the explosion. 161,000 people had to be evacuated from a 30 kilometer radius of the reactor and 25,000 square km of land were contaminated. As time went on millions of people suffered radiation related health problems such as leukemia and thyroid cancer and around 4,000 people have died as a result of the long-term effects of the accident.
Nobody was prepared for such a crisis. For the next seven months, 500,000 men will wage hand-to-hand combat with an invisible enemy -- a ruthless battle that has gone unsung, which claimed thousands of unnamed and now almost forgotten heroes. Yet, it is thanks to these men that the worst was avoided; a second explosion, ten times more powerful than Hiroshima which would have wiped out more than half of Europe. This was kept secret for twenty years by the Soviets and the West alike.

On January 3 1961SL1 reactor was being prepared for a restart following a maintenance outage. The control rods were being withdrawn to reconnect them to the drive mechanism, when suddenly one rod was removed to far, causing the reactor to become prompt-critical. The resulting power surge led to an explosive vaporization of the water, which in turn created a water hammer, ejecting the control rods and the shield plugs.

Documentary film covering the top secret 1959SodiumReactor meltdown in Los Angeles, California. The incident, kept secret for decades, resulted in the deaths of an estimated 300 to 1,800 people and is the suspected source of elevated cancer rates in adjacent suburban communities. The amount of contaminants released have been estimated at over 400 times that of the highly publicized Three Mile Island incident. This film features accounts from former Atomics International employees detailing the incident that sent highly radioactive gases over parts of Los Angeles for two weeks. Employees also recall illegal acts of mass pollution such as open burn pits that sent radioactive waste into the open air for decades. These experiments took place at the Santa Susana Field Laboratory, in the hills between Los Angeles' San Fernando Valley and Simi Valley.
The film gathers comprehensive incident footage and testimonial interviews with local survivors, physicians, scientists, researchers and reporters regarding the 1959 meltdown and the grassroots movements to clean the site in order to save generations from exposure to it's migrating contaminants. PLEASE SHARE THIS FILM!! PEOPLE DESERVE TO KNOW THE TRUTH.

Named after the Buddhist divinity of wisdom, Monju, located in Japan's Fukui prefecture, is Japan's only fast-breeder reactor. Unlike conventional reactors, fast-breeder reactors, which "breed" plutonium, use sodium rather than water as a coolant. This type of coolant creates a potentially hazardous situation as sodium is highly corrosive and reacts violently with both water and air.
On December 8th, 1995, 700 kg of molten sodium leaked from the secondary cooling circuit of the Monju reactor, resulting in a fire that made headlines across the country. Although the accident itself did not result in a radiation leak, many argue that the fire came close to breaching Monju, a catastrophe which would have spilled plutonium into the environment.
Following the fire, officials at the government-owned PowerReactor and NuclearFuelDevelopment Corporation (PNC), operators of Monju, first played down the extent of damage at the reactor and denied the existence of a videotape showing the sodium spill. Later, they released still shots only, showing things like intact pipes and clean floors and claiming that there had only been "a minor leakage in the secondary sodium loop [that had] caused some fumes". While short videos were released, these were edited to hide the full extent of the damage. Further complicating the story, the deputy general manager of the general affairs department at the PNC, Shigeo Nishimura, 49, jumped to his death the day after a news conference where he and other officials revealed the extent of the cover-up.
Starting from September of 2007, Nishimura's family brought the story back to light in a trial against the PNC at Japan's High Court.

The Chernobyl disaster
was a nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine (officially Ukrainian SSR), which was under the direct jurisdiction of the central Moscow's authorities. An explosion and fire released large quantities of radioactive contamination into the atmosphere, which spread over much of WesternUSSR and Europe. It is considered the worst nuclear power plant accident in history atleast until Fukushima, and is one of only three classified as a level 7 event on the International Nuclear Event Scale (the other being the Fukushima Daiichi nuclear disaster).
The battle to contain the contamination and avert a greater catastrophe ultimately involved over 500,000 workers and cost an estimated 18 billion rubles, crippling the Soviet economy.
The disaster began during a systems test on Saturday, 26 April 1986 at reactor number four of the Chernobyl plant, which is near the city of Prypiat and within a close proximity to the administrative border with Belarus and Dnieper river. There was a sudden power output surge, and when an emergency shutdown was attempted, a more extreme spike in power output occurred, which led to a reactor vessel rupture and a series of explosions. These events exposed the graphite moderator of the reactor to air, causing it to ignite.
The resulting fire sent a plume of highly radioactive smoke fallout into the atmosphere and over an extensive geographical area, including Pripyat. The plume drifted over large parts of the western Soviet Union and Europe. From 1986 to 2000, 350,400 people were evacuated and resettled from the most severely contaminated areas of Belarus, Russia, and Ukraine.
According to official post-Soviet data, about 60% of the fallout landed in Belarus.
The accident raised concerns about the safety of the Soviet nuclear power industry, as well as nuclear power in general, slowing its expansion for a number of years and forcing the Soviet government to become less secretive about its procedures.
The government coverup of the Chernobyl disaster was a "catalyst" for glasnost, which "paved the way for reforms leading to the Soviet collapse."
Russia, Ukraine, and Belarus have been burdened with the continuing and substantial decontamination and health care costs of the Chernobyl accident. A report of the International Atomic Energy Agency,
examines the environmental consequences of the accident. Estimates of the number of deaths potentially resulting from the accident vary enormously: Thirty one deaths are directly attributed to the accident, all among the reactor staff and emergency workers.
A UNSCEAR report places the total confirmed deaths from radiation at 64 as of 2008. The World Health Organization (WHO) suggests it could reach 4,000 civilian deaths, a figure which does not include military clean-up worker casualties.
A 2006 report predicted 30,000 to 60,000 cancer deaths as a result of Chernobyl fallout.
A Greenpeace report puts this figure at 200,000 or more. A Russian publication, Chernobyl, concludes that 985,000 premature cancer deaths occurred worldwide between 1986 and 2004 as a result of radioactive contamination from Chernobyl.

The Fukushima disaster is the largest nuclear disaster since the 1986 Chernobyl disaster and the second disaster to be given the Level 7 event classification of the International Nuclear Event Scale. Though there have been no fatalities linked to radiation due to the accident, the eventual number of cancer deaths, according to the linear no-threshold theory of radiation safety, that will be caused by the accident is expected to be around 130-640 people in the years and decades ahead. The United Nations Scientific Committee on the Effects of AtomicRadiation and World Health Organization report that there will be no increase in miscarriages, stillbirths or physical and mental disorders in babies born after the accident. However, an estimated 1,600 deaths are believed to have occurred due to the resultant evacuation conditions. There are no clear plans for decommissioning the plant, but the plant management estimate is 30 or 40 years. A frozen soil barrier is being constructed to prevent further contamination of seeping groundwater by melted-down nuclear fuel.

Fifty years ago, on the night of 10 October1957, Britain was on the brink of an unprecedented nuclear tragedy. A fire ripped through the radioactive materials in the core of Windscale, Britain's first nuclear reactor. Tom Tuohy, the deputy general manager at the site, led the team faced with dealing with a nightmare no-one had thought possible.
"Mankind had never faced a situation like this; there's no-one to give you any advice," he said. Tuohy and his men were confronted by a terrifying dilemma.
If they let the fire burn out, it could spread radioactivity over a large area of Britain. But if they put water on the reactor, they risked turning it into a nuclear bomb that could kill them all.
Now tapes of the inquiry into the accident, heard for the first time in a BBC film, reveal the reasons why the politicians covered up the causes of the accident. Scientists had been warning about the dangers of an accident for some time. The safety margins of the radioactive materials inside the reactor were being further and further eroded.
"They were running much too close to the precipice," says Dr Dunworth, a senior manager in the NuclearResearch Laboratory in Harwell, Oxfordshire, who was one of those highlighting the potential dangers.
But the politicians and the military ignored the warnings; instead they increased demands on Windscale to produce material for an H-bomb.
For 50 years, the official record on the accident has been that the very men who had averted a potentially devastating accident were to blame for causing it.
"I resented it at the time," says Peter Jenkinson, who was an assistant physicist at the reactor, "and I hoped the record would be put straight." After the inquiry, he and his colleagues finally got their wish.

http://en.wikipedia.org/wiki/SL-1
The SL-1, or Stationary Low-Power Reactor Number One, was a United States Army experimental nuclear power reactor which underwent a steam explosion and meltdown on January 3, 1961, killing its three operators. The direct cause was the improper withdrawal of the central control rod, responsible for absorbing neutrons in the reactor core. The event is the only known fatal reactor incident in the United States. The incident released about 80 curies (3.0 TBq) of iodine-131, which was not considered significant due to its location in a remote desert of Idaho. About 1,100 curies (41 TBq) of fission products were released into the atmosphere.
The facility, located at the National Reactor Testing Station (NRTS) approximately 40 miles (64 km) west of Idaho Falls, Idaho, was part of the Army Nuclear Power Program and was known as the Argonne Low Power Reactor (ALPR) during its design and build phase. It was intended to provide electrical power and heat for small, remote military facilities, such as radar sites near the Arctic Circle, and those in the DEW Line. The design power was 3 MW (thermal). Operating power was 200 kW electrical and 400 kW thermal for space heating.
In the incident the core power level reached nearly 20 GW in just four milliseconds, precipitating the steam explosion...
From 1954 to 1955, the U.S. Army evaluated their need for nuclear reactor plants that would be operable in remote regions of the Arctic. [The Army] contracted with Argonne National Laboratory to design, build, and test a prototype reactor plant to be called the Argonne Low Power Reactor (ALPR)...
Incident and response
On December 21, 1960, the reactor was shut down for maintenance, calibration of the instruments, installation of auxiliary instruments, and installation of 44 flux wires to monitor the neutron flux levels in the reactor core. The wires were made of aluminum, and contained slugs of aluminum--cobalt alloy.
On January 3, 1961, the reactor was being prepared for restart after a shutdown of eleven days over the holidays. Maintenance procedures were in progress, which required the main central control rod to be manually withdrawn a few inches to reconnect it to its drive mechanism; at 9:01 p.m. this rod was suddenly withdrawn too far, causing SL-1 to go prompt critical instantly. In four milliseconds, the heat generated by the resulting enormous power surge caused water surrounding the core to begin to explosively vaporize. The water vapor caused a pressure wave to strike the top of the reactor vessel, causing water and steam to spray from the top of the vessel. This extreme form of water hammer propelled control rods, shield plugs, and the entire reactor vessel upwards. A later investigation concluded that the 26,000-pound (12,000 kg) vessel had jumped 9 feet 1 inch (2.77 m) and the upper control rod drive mechanisms had struck the ceiling of the reactor building prior to settling back into its original location. The spray of water and steam knocked two operators onto the floor, killing one and severely injuring another. One of the shield plugs on top of the reactor vessel impaled the third man through his groin and exited his shoulder, pinning him to the ceiling. The victims were Army SpecialistsJohn A. Byrnes (age 27) and RichardLeroy McKinley (age 22), and Navy Seabee Construction ElectricianFirst Class (CE1) Richard C. Legg (age 26). It was later established that Byrnes (the reactor operator) had lifted the rod and caused the excursion, Legg (the shift supervisor) was standing on top of the reactor vessel and was impaled and pinned to the ceiling, and McKinley, the trainee who stood nearby, was later found alive by rescuers. All three men succumbed to injuries from physical trauma, however the radiation from the nuclear excursion would have given the men no chance of survival...
There were no other people at the reactor site. The ending of the nuclear reaction was caused solely by the design of the reactor and the basic physics of heated water and core elements melting, separating the core elements and removing the moderator...
The remains of the SL-1 reactor are now buried near the original site...

11. GoianiaAccident, Brazil
One of the worst nuclear contamination incidents in the world took place in Goiania, Brazil. A radiotherapy institute in the city had relocated, leaving behind a teletherapy unit that still contained cesium chloride.
On September 13, 1987, two scavengers found the unit, carted it away in a wheelbarrow, and sold it to a junkyard. The owner invited friends and family to see the glowing blue material inside, inadvertently exposing them to radiation. All of them then went their separate ways and irradiated friends and family all over the city.
In all, 245 people were exposed to radiation and four people passed. It raised awareness that sources of radiation must be controlled from ‘cradle to grave’ to prevent the public accessing them.
10. Windscale Pile, EnglandBritain needed plutonium and other materials for the country’s burgeoning nuclear weapons. In the late 1940s, they built their first nuclear reactor, called Windscale, in northwest England. On October 10, 1957, workers conducting standard maintenance at the massive facility noticed rising temperatures. Upon further inspection, they discovered that the reactor’s uranium-filled graphite core had caught fire. Worse, it had likely been ablaze for two days, releasing dangerous contaminants into the atmosphere.
With the reactor on the verge of collapse, plant operators fought the flames with cooling fans, carbon dioxide, and water. The fire finally died out on October 12, but by that time, a radioactive cloud was already spreading across the United Kingdom and Europe.
While no evacuations occurred, officials prohibited the sale of milk from the affected area for roughly a month. An investigation discovered the accident had been both avoidable and mishandled. The British government suppressed the complete report for several decades, however, in part because it may have compromised Britain’s efforts to cooperate with the United States on nuclear development. In 2007, a study estimated that the radioactive fallout from the Windscale fire might have caused some 240 cases of cancer.
9. Three Mile Island, Pennsylvania
The most serious nuclear accident in U.S. history took place at the Three Mile Island plant near Harrisburg, Pennsylvania, a brand-new facility lauded for its state-of-the-art design, efficiency and affordability during an era of energy crises. It began in the early hours of the morning, when a pressure valve in one of the reactors failed to close, allowing cooling water–contaminated with radiation–to drain into adjoining buildings. Control room operators made critical errors as they struggled to contain the crisis, and the core had heated to over 4,000 degrees–just 1,000 degrees short of meltdown.
As radioactive steam began pouring out of the plant, word of the incident leaked to the outside world. The plant’s parent company downplayed the event, claiming that no radiation had been detected off plant grounds. However, within days radiation levels were elevated over a four-county zone. Pennsylvania GovernorRichard Thornburgh ordered the evacuation of pregnant women and small children from the area.
The incident also eroded the American public’s faith in nuclear power, inspiring many demonstrations, and increased awareness of the need for emergency preparedness at the state and local levels. Over 50 nuclear plant construction projects were cancelled in just four years, and the number of ongoing projects declined from 1980 until 1998.

Compilation of Rare 1986 Videos of Chernobyl Disaster. (English)

On April 26, 2016, Ukraine marked the sad 30th anniversary of the Chornobyl nuclear disaster.
The Chernobyl disaster was a catastrophic nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in the city of Pripyat, then located in the Ukrainian Soviet Socialist Republic of the Soviet Union (USSR). An explosion and fire released large quantities of radioactive particles into the atmosphere, which spread over much of the western USSR and Europe.
https://en.wikipedia.org/wiki/Chernobyl_disaster
Moscow tried to hide the disaster for 2 days before finally admitting the accident. Evacuation began long before the accident was publicly known throughout the Union. Only on 28 April, after radiation levels set off alarms at the Forsmark Nuclear Power Plant in Sweden, over 1,000 kilometres (620 mi) from the Chernobyl Plant, did the Soviet Union publicly admit that an accident had occurred. At 21:02 that evening a 20-second announcement was read in the TV news program Vremya:
There has been an accident at the Chernobyl Nuclear Power Plant. One of the nuclear reactors was damaged. The effects of the accident are being remedied. Assistance has been provided for any affected people. An investigative commission has been set up.
— Vremya, 28 April 1986 (21:00)
This was the entirety of the announcement of the accident.
The nearby city of Pripyat was not immediately evacuated. The townspeople went about their usual business, completely oblivious to what had just happened. By 11:00 on 27 April, buses had arrived in Pripyat to start the evacuation.
Thirty-one deaths are directly attributed to the accident, all among the reactor staff and emergency workers. An UNSCEAR report places the total confirmed deaths from radiation at 64 as of 2008. The Chernobyl Forum predicts the eventual death toll could reach 4,000 among those exposed to the highest levels of radiation (200,000 emergency workers, 116,000 evacuees and 270,000 residents of the most contaminated areas).
The soundtrack is "Ethnicolor 1" by Jean Michel Jarre.

The impact of nuclear accidents has been a topic of debate practically since the first nuclear reactors were constructed in 1954. It has also been a key factor in public concern about nuclear facilities. Some technical measures to reduce the risk of accidents or to minimize the amount of radioactivity released to the environment have been adopted. Despite the use of such measures, human error remains, and "there have been many accidents with varying impacts as well near misses and incidents".

SEOUL, South Korea — North Korea renewed its threat to boycott an upcoming summit with PresidentDonald Trump, saying Thursday that it’s up to the United States to decide whether it wants to meet in a room or face a “nuclear-to-nuclear showdown.” ... will meet us at a meeting room or encounter us at nuclear-to-nuclear showdown is entirely dependent upon the decision and behavior of the United States.”....

The Battle Of Chernobyl (Full Documentary)

The Chernobyl disaster was a catastrophic nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine (then officially the Ukrainian SSR), which was under the direct jurisdiction of the central authorities of the Soviet Union. An explosion and fire released large quantities of radioactive particles into the atmosphere, which spread over much of the western USSR and Europe.
The Chernobyl disaster is widely considered to have been the worst nuclear power plant accident in history, and is one of only two classified as a level 7 event (the maximum classification) on the International Nuclear Event Scale (the other being the Fukushima Daiichi nuclear disaster in 2011).
The battle to contain the contamination and avert a greater catastrophe ultimately involved over 500,000 workers and cost an estimated 18 billion rubles.The official Soviet casualty count of 31 deaths has been disputed, and long-term effects such as cancers and deformities are still being accounted for.
It's a documentary which analyzes the Thursday 26th April1986 that became a momentous date in modern history, when one of the reactors at the Chernobyl nuclear power station in northern Ukraine, exploded. It was the most significant reactor failure in the history of nuclear power, a Maximum Credible Accident (MCA). The plant, just 20 km away from the town center, was made up of four reactor units each generating an output of 1,000 megawatts. The reactor in question exploded due to operational errors and inadequate safety measures and the meltdown was directly linked to routine testing on the reactor unit's turbine generators.
The test required reactor activity and the thermal reactor output to be run down to a lower level. During the procedure, however, the reactor plummeted to an unexpectedly low and unstable level of activity. At this point, it should have been shut down; as the operators chose to continue with the test, the events subsequently proved to be catastrophic.
More than 200 people died or were seriously injured by radiation exposure immediately after the explosion. 161,000 people had to be evacuated from a 30 kilometer radius of the reactor and 25,000 square km of land were contaminated. As time went on millions of people suffered radiation related health problems such as leukemia and thyroid cancer and around 4,000 people have died as a result of the long-term effects of the accident.
Nobody was prepared for such a crisis. For the next seven months, 500,000 men will wage hand-to-hand combat with an invisible enemy -- a ruthless battle that has gone unsung, which claimed thousands of unnamed and now almost forgotten heroes. Yet, it is thanks to these men that the worst was avoided; a second explosion, ten times more powerful than Hiroshima which would have wiped out more than half of Europe. This was kept secret for twenty years by the Soviets and the West alike.

SL1 Accident (1961)

On January 3 1961SL1 reactor was being prepared for a restart following a maintenance outage. The control rods were being withdrawn to reconnect them to the drive mechanism, when suddenly one rod was removed to far, causing the reactor to become prompt-critical. The resulting power surge led to an explosive vaporization of the water, which in turn created a water hammer, ejecting the control rods and the shield plugs.

Documentary film covering the top secret 1959SodiumReactor meltdown in Los Angeles, California. The incident, kept secret for decades, resulted in the deaths of an estimated 300 to 1,800 people and is the suspected source of elevated cancer rates in adjacent suburban communities. The amount of contaminants released have been estimated at over 400 times that of the highly publicized Three Mile Island incident. This film features accounts from former Atomics International employees detailing the incident that sent highly radioactive gases over parts of Los Angeles for two weeks. Employees also recall illegal acts of mass pollution such as open burn pits that sent radioactive waste into the open air for decades. These experiments took place at the Santa Susana Field Laboratory, in the hills between Los Angeles' San Fernando Valley and Simi Valley.
The film gathers comprehensive incident footage and testimonial interviews with local survivors, physicians, scientists, researchers and reporters regarding the 1959 meltdown and the grassroots movements to clean the site in order to save generations from exposure to it's migrating contaminants. PLEASE SHARE THIS FILM!! PEOPLE DESERVE TO KNOW THE TRUTH.

Named after the Buddhist divinity of wisdom, Monju, located in Japan's Fukui prefecture, is Japan's only fast-breeder reactor. Unlike conventional reactors, fast-breeder reactors, which "breed" plutonium, use sodium rather than water as a coolant. This type of coolant creates a potentially hazardous situation as sodium is highly corrosive and reacts violently with both water and air.
On December 8th, 1995, 700 kg of molten sodium leaked from the secondary cooling circuit of the Monju reactor, resulting in a fire that made headlines across the country. Although the accident itself did not result in a radiation leak, many argue that the fire came close to breaching Monju, a catastrophe which would have spilled plutonium into the environment.
Following the fire, officials at the government-owned PowerReactor and NuclearFuelDevelopment Corporation (PNC), operators of Monju, first played down the extent of damage at the reactor and denied the existence of a videotape showing the sodium spill. Later, they released still shots only, showing things like intact pipes and clean floors and claiming that there had only been "a minor leakage in the secondary sodium loop [that had] caused some fumes". While short videos were released, these were edited to hide the full extent of the damage. Further complicating the story, the deputy general manager of the general affairs department at the PNC, Shigeo Nishimura, 49, jumped to his death the day after a news conference where he and other officials revealed the extent of the cover-up.
Starting from September of 2007, Nishimura's family brought the story back to light in a trial against the PNC at Japan's High Court.

Zero Hour: Disaster at Chernobyl Discovery Channel (2004)

New clothing line: https://shop.spreadshirt.com/finesthq/
The explosion at Chernobyl was ten times worse than that at Hiroshima and was due to a combination of human error and imperfect technology. Using a real-time split-screen format reminiscent of the hit series, 24, this programme examines the 60 critical minutes leading up to the explosion at the power station on 26th April1986.
Each minute unfolds narrating the events from the perspectives of key characters involved including Chernobyl's deputy chief engineer and his staff in the control room as well as innocent bystanders, the wife of one of Chernobyl's workers and two fishermen working in Chernobyl's warm waste waters.
With an extraordinary combination of drama and state of the art CGI graphics, Disaster at Chernobyl climaxes with the reconstructon of the final seconds leading to the disaster, the explosion itself and its terrifying aftermath.

Disaster At Chernobyl.

The Chernobyl disaster
was a nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine (officially Ukrainian SSR), which was under the direct jurisdiction of the central Moscow's authorities. An explosion and fire released large quantities of radioactive contamination into the atmosphere, which spread over much of WesternUSSR and Europe. It is considered the worst nuclear power plant accident in history atleast until Fukushima, and is one of only three classified as a level 7 event on the International Nuclear Event Scale (the other being the Fukushima Daiichi nuclear disaster).
The battle to contain the contamination and avert a greater catastrophe ultimately involved over 500,000 workers and cost an estimated 18 billion rubles, crippling the Soviet economy.
The disaster began during a systems test on Saturday, 26 April 1986 at reactor number four of the Chernobyl plant, which is near the city of Prypiat and within a close proximity to the administrative border with Belarus and Dnieper river. There was a sudden power output surge, and when an emergency shutdown was attempted, a more extreme spike in power output occurred, which led to a reactor vessel rupture and a series of explosions. These events exposed the graphite moderator of the reactor to air, causing it to ignite.
The resulting fire sent a plume of highly radioactive smoke fallout into the atmosphere and over an extensive geographical area, including Pripyat. The plume drifted over large parts of the western Soviet Union and Europe. From 1986 to 2000, 350,400 people were evacuated and resettled from the most severely contaminated areas of Belarus, Russia, and Ukraine.
According to official post-Soviet data, about 60% of the fallout landed in Belarus.
The accident raised concerns about the safety of the Soviet nuclear power industry, as well as nuclear power in general, slowing its expansion for a number of years and forcing the Soviet government to become less secretive about its procedures.
The government coverup of the Chernobyl disaster was a "catalyst" for glasnost, which "paved the way for reforms leading to the Soviet collapse."
Russia, Ukraine, and Belarus have been burdened with the continuing and substantial decontamination and health care costs of the Chernobyl accident. A report of the International Atomic Energy Agency,
examines the environmental consequences of the accident. Estimates of the number of deaths potentially resulting from the accident vary enormously: Thirty one deaths are directly attributed to the accident, all among the reactor staff and emergency workers.
A UNSCEAR report places the total confirmed deaths from radiation at 64 as of 2008. The World Health Organization (WHO) suggests it could reach 4,000 civilian deaths, a figure which does not include military clean-up worker casualties.
A 2006 report predicted 30,000 to 60,000 cancer deaths as a result of Chernobyl fallout.
A Greenpeace report puts this figure at 200,000 or more. A Russian publication, Chernobyl, concludes that 985,000 premature cancer deaths occurred worldwide between 1986 and 2004 as a result of radioactive contamination from Chernobyl.
